パーティションを切る / partisioning

WD 3200 にパーティションを切る。
partisioning the WD3200.

root@LS-WSGL678:~# fdisk /dev/sdb

The number of cylinders for this disk is set to 38913.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
